Cypress Semiconductor is sampling new devices in its Traveo automotive microcontroller (MCU) family that provides secure, high-speed networking for classic instrument cluster applications.
The new MCUs support the Controller Area Network Flexible Data-rate (CAN FD) standard for high-speed, in-vehicle networking, allowing large amounts of data to be exchanged between each CAN node. Integrated enhanced Secure Hardware Extension (eSHE) support enables the devices to secure data on in-vehicle networks and prevent unauthorised connections to electronic control units (ECUs). The chips offer advanced system features, high-quality sound and graphics, and can drive up to six traditional mechanical gauges.
The new Traveo S6J336xx and S6J337xx series leverage Cypress’ 40 nm embedded charge-trap (eCT) Flash technology for higher performance and reliability. They are based on an ARM Cortex-R5 core with robust, 132 MHz performance and feature up to 2 MB of high-density embedded Flash for application storage.
The MCUs offer an LCD interface that supports 4com x 32 segment, which can be used for a basic LCD display such as the odometer. The interface also supports TFT display sizes up to 480x240 pixels with a sequencer that simplifies control of the meter display, which can be used to show simple diagnostics such as tyre pressure or that a door is open.
A partial wake-up mode allows the MCUs to operate some functions while the core is in sleep mode and to only wake up if needed, enabling the lowest possible system power consumption. The MCUs also support on-chip sound mixing, eliminating the need for an external mixing IC.
Cypress offers a broad range of variations in the series that enables customers to easily develop derivative solutions.
The new Traveo MCUs include the S6J351Cx series, which are targeted for body electronics applications. The series also leverages Cypress’ 40 nm eCT Flash technology and integrate an ARM Cortex-R5 core with 132 MHz performance, along with up to 2 MB of high-density embedded Flash for application storage.
